Gary Joran Mayoralgo posted about how his cousin wasn't able to come back home.
The last information they had was the place where he went. Paul Anthony Miranda Esguerra had went to Manila Bay. They were unsure since they are using his facebook posts as basis so he is either in Manila Bay, Nangka Marikina or Cubao.
Another thing to consider is the peculiarity of his facebook posts that indicates "dead" and telling people goodluck in finding his corpse. Is this a premonition?
